hi got Nikon d800 and the trinity lens spent a lot a money on the gear but never thought how good my cheep monitor was Samsung SyncMaster P2270HD
so thinking on splashing out but whats the benefits of a wide gamut monitor for printing when print is in sRGB
1 NEC PA241W
2 dell u2413
Wide gamut will be of zero benefit to you if you work in sRGB. However, most high end screens are wide gamut anyway, so don't worry about it.
The NEC is a far superior screen to the Dell. Higher resolution LUT (although this is academic, as it's not programmable*, so when you profile you're still doing it at 8 bit level at your GPU.. not the screen). Better anti-glare coating, better built, better image quality (even display, back light bleed, black levels), but has poor connectivity compared to the Dell. The NEC has poor calibration straight out of the box though and really needs profiling.
*The NEC PA241 CAN be hardware profiled, but you need Spectraview II software from the US website. It's not shipped with it in Europe. You can't just download this though as you need a serial number to use it. As it is, shipped in Europe, it does not come with Spectraview and can't be hardware profiled. The Dell can't either though.
Both screens are good though, and either would be a worthwhile upgrade.
As for monitors in general, I think they're every bit as important as your camera. It's what you interface with for hours and hours at a time, and it's the device that controls, ultimately, what your images look like to other people. I paid more for my screen than I did for my camera.
Whatever you buy, budget for a calibrator. i1 Display Pro is a good choice, and if you need print profiling too, Color Munki Photo.
The best screen in the world, uncalibrated, may as well be a cheap screen.
